I sEcoNnARY RACK; 4

Application filed July 27, 1923. Serial No. 654,157.

The invention relatesto secondary racks. The ob ect of the invention 15 to provide a secondary rack, more particularly for use on line poles and other suitable supports, in

which the usual base and separate insulator supporting arms or brackets are dispensed with, thereby reducing the number of parts that constitute the rack to a minimum an producing a rack at such a low cost that' 7 particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is an elevation of a rack embodying the invention; Fig. 2 is a view generally similar to Fig. 1 with the addition of a means for reinforcing the rack; and Fig. 3 is a detail sectional view taken on the line 3-3 of Fig. 2.

In the drawingsthe numeral 4 designates a U-shaped metal memberf conveniently formed from a round bar. The legs5 of v the member 4 are designed to extend through the pole 6. a cross-arm, or other suitable support, and to space the transverse portion 7 of the member 4 at the desired distance from the support. The ends 8 of the legs are threaded to take nuts 9 and the member is clamped to its support between a suitable shouldered portion or stop projection formed on each leg and the nut 9, which nut may engage against'a washer 10 abutting against the support. The shouldered portion here shown consists of a plurality of ribs or projections 11 struck up from the rod which may engage against a washer 12. It will thus be noted that the end portions ofv the legs 5 of the member 4 are designed to form bolts to clamp the rack to its support.

The insulators 13are placed on the member 4 prior to bending the end portions of saidmember' into legs and they 'may'be secured thereon against, longitudinal displacement in any suitable manner. As

shown the transverse portion of the member 4 has ribs 14 struck up therefrom near the legs to form stop projections, and those invsulators nearestthe legs are held. between these projections and cotter pins 15inS6 -(1 in openings in the member 4, washers 16 being preferably provided between the ends of the insulator and the ribs 14 and pins 15. The intermediate insulator or insulators 13 may be heldagainst longitudinal movement by cotter pins 17 inserted in'openings in said member 4, and washers 18 may also be Where the span between the legs of the member is considerable so that there is a tendency for the transverse portion of the member 4 to bow when subjected to line strains, a reinforcing member 19 having an eyed or hooked portion 2O engag1ng the .inember 4 has its shank 21 passed through vention is not to be limited to any specific formor arrangement of parts except 1n so far as such limitations are specified in the claims.

What I claim as my invention is:

1-; A secondary rack comprising a U- shaped' member having integral leg portions each adapted to extend through a rack support and be clamped thereto, and insula- I tors spacedly mounted on. and receiving therethrough the transverse portion of said member and maintained against longitudinal displacement.

2A secondary rack comprising a U- shaped member having integral leg por tions each adapted to extend through a rack support, said leg portions having threaded nut-receiving ends and intermediately disposed shouldered portions cooperating therewith to clamp said member to its support and to space the transverse portion of said member from the support, and insulators mounted on and receiving therethrough the transverse portion of said member.

3. A secondary rack comprising a U- shaped member having leg portions each adapted to be clamped to a rack support, insulators mounted on the transverse portion of said member. and a hooked bolt member engaging said transverse portion at an intermediate point and having a threaded portion clamped to the support to reinforce d used between said pins and each insulator.

said U-shaped member against bending strains.

A secondary rack comprising a'U- shaped member having integral leg portions each adapted to be clamped to a rack support, insulators mounted on the transverse portion of said ni'e'mber, and a reinforcing member having a hooked part engaging said t'ansverse portion at an in- 10 t'GlIllCCllittB point and a part adapted to' extend through said support and be clamped thereto. a

A secondary rack comprising a U- shaped rod having integral parallel boltended le portions for entrance into a support, and apertured insulators mounted on and receiving theretl'irough the transverse portionof said rod.

In testimony whereof I aflix my signature.
